garjus

Garjus processes imaging data stored in REDCap and XNAT. All related settings are stored in REDCap. Each automation that runs is logged in REDCap. Any issues encountered are recorded in REDCap. Progress snapshots are stored in REDCap. Current views are in the dashboard.

Garjus is the interface to everything that's stored in XNAT/REDCap. It uses REDCap to store it's own settings and tracking data. Anytime we want to access these data in REDCap or XNAT in python or CLI, we use Garjus in between. Creating a Garjus instance means setting up the interfaces with XNAT/REDCap.

The main Garjus class provides these data access methods that all return a Pandas DataFrame:

activity()
analyses()
assessors()
automations()
issues()
phantoms()
processing_protocols()
progress()
scans()
subjects()
subject_assessors()
stats(project)
tasks()

To get the columns in each dataframe:

column_names(type)
e.g. 
column_names('issues')
or
column_names('scans')

These Garjus methods returns names in a list:

stattypes(project)
scantypes(project)
proctypes(project)
stats_assessors(project)
stats_projects()

Command-line interface subcommands:

activity - display activity
analyses - display analyses
compare - run data entry comparison
copysess - copy an imaging session from one project to another
d2q - apply updates from dax queue on local disk to garjus task queue in REDCap
dashboard - start a dashboard server and browse to it in a new local web browser tab
delete - delete a proctype from a project
getinputs - download inputs for an analysis
image03csv - create an NDA image03 formatted csv file for a project and date range
image03download - download all images for an NDA image03 csv file
importdicom - import DICOM into XNAT from local file or remote URL
issues - display issues
pdf
processing
progress
q2d - apply updates from garjus REDCap queue to dax local disk queue by writing new batch scripts
quicktest - test connections
report - creates a summary PDF
retry - find jobs that have run once an run them again
run
setsesstype
setsite
stats
subjects
tasks
update

Scanning Automations:

• xnat_auto_archive - archives scans in XNAT

• xnat_session_relabel - modifies labels in XNAT based on a set of rules to set the site and session type

• xnat_scan_relabel - relabels scan type in XNAT using a simple map of input to output labels

EDAT Automations:

• edat_convert - convert files, input is from redcap file field, outputs to redcap file field

• edat_limbo2redcap - load files from a local folder

• edat_redcap2xnat - copy edat files from REDCap to XNAT

• edat_etl - extract data from files uploaded to redcap, transform (calculate accuracy, times), load to redcap

• nihtoolbox_etl - extract and load NIH toolbox outputs

• examiner_etl - extract and load NIH Examiner outputs

Issues

Any issues or errors encountered by garjus are recorded in REDCap. Issues are automatically resolved when the error or issues is no longer found. Resolved issues are deleted one week after resolution.

Activity

Each complete automation is recorded in activity.

Set up

Create a new Garjus main REDCap project:

• upload from zip (see misc folder)
• click user rights, enable API export/import, save changes
• refresh, click API, click Generate API Token, click Copy
• go to ~/.redcap.txt
• paste key, copy & paste PID from gui, name it "main"

Create first stats REDCap project:

• upload from zip (see misc folder)
• click user rights, check enable API export/import, click save changes
• Refresh page, click API, click Generate API Token, click Copy
• Go to ~/.redcap.txt
• Paste key, copy & paste ID, name
• Paste ID into ccmutils under Main > Project Stats

Create additional stats REDCap projects:

• Copy an existing project in gui under Other Functionality, click Copy Project
• Change the project name
• Confirm checkboxes for Users, Folder
• Click Copy Project (should take you to new project)
• In the new project, click user rights, check enable API export/import, click save changes
• Refresh page, click API, click Generate API Token, click Copy
• Go to ~/.redcap.txt
• Paste key, copy & paste ID, name main
• Paste ID into ccmutils under Main > Project Stats

Add a new primary REDCap project to link individual study to garjus:

• Copy PID, key to ~/.redcap.txt, name PROJECT primary
• paste ID into ccmutils under Main > Project Primary

Add a new secondary REDCap project for double entry comparison:

• Copy PID, key to ~/.redcap.txt, name PROJECT secondary
• paste ID into ccmutils under Main > Project Secondary

Quickstart

pip install garjus

or

pip install git+https://github.com/bud42/garjus.git

or

pip install git+https://github.com/bud42/garjus.git@v1.0.0

QA Dashboard without REDCap, only XNAT

The garjus QA dashboard can be used with only XNAT access. First, you'll need credentials in your home directory. The same as dax, you need a .netrc file in your home directory with machine, login, and password in plain text. This file should only be readable by the owner.

machine xnat.vanderbilt.edu
login XNAT_USERNAME
password XNAT_PASSWORD

Then install garjus and launch the dashboard. To install in a new python 3 environment:

python -m venv venv-garjus

Then load the new virtual environment with:

source venv-garjus/bin/activate

And then install garjus in the venv with:

pip install garjus

If you encounter an error with scikit learn, you can bypass it with:

export SKLEARN_ALLOW_DEPRECATED_SKLEARN_PACKAGE_INSTALL=True && pip install garjus

After garjus is successfully installed, you can launch a dashboard with:

garjus dashboard

This should open a new tab in your web browser at the dashboard main page http://localhost:8050 . Choose one or more projects from the drop down. The options should include all projects that are accessible to your XNAT account using the credentials in your .netrc file. Find a problem? Please report an issue. Got an idea? Open a Discussion.
